Looking for data on the orbit of S2 star

[Moss Pauly]

Hello,
I'm doing a project on proving the existence of black holes. I am using Sgr-A as a test subject and am after the data set for the orbit of the star S2 around it so I can do some of my own calculations on it. Does anyone know where i might be able to obtain these?

This paper has the orbital elements of 28 stars orbiting around the central black hole, including S2. Happy hunting!
